A recently filed patent (Publication Number: US20240026729A1) outlines a method for creating a vacuum insulated glazing unit. The method involves applying a primary sealant to a first pane, positioning support pillars and an evacuation tube on the pane, placing a second pane on the support pillars, and heating the primary sealant with a laser beam to form a seal between the two panes. The intermediate space between the panes is then evacuated to create a low-pressure environment, and the evacuation tube is sealed to maintain this environment within the unit. Additionally, a secondary sealant can be applied to function as a getter material after sealing the evacuation tube.
Furthermore, the patent describes the vacuum insulated glazing unit itself, which includes the first and second panes, a primary seal, support pillars, and an evacuation tube. The primary seal joins the panes along their perimeters, creating an intermediate space that is hermetically sealed to maintain a low-pressure environment. The unit can also feature a secondary seal acting as a getter material, and both seals are made of glass materials. The coefficient of thermal expansion values of the primary seal and evacuation tube are compatible with those of the panes, ensuring structural integrity. Overall, the vacuum insulated glazing unit is designed to be installed as a component of a fenestration unit, offering improved insulation properties for various applications.
